Poisson's ratio in cryocrystals under pressure
Yu. A. Freiman, Alexei Grechnev, S. M. Tretyak +2
We present results of lattice dynamics calculations of Poisson's ratio (PR) for solid hydrogen and rare gas solids (He, Ne, Ar, Kr and Xe) under pressure. Using two complementary a…
Pressure induced metallization with absence of structural transition in layered MoSe2
Zhao Zhao, Haijun Zhang, Hongtao Yuan +10
Layered transition-metal dichalcogenides have emerged as exciting material systems with atomically thin geometries and unique electronic properties. Pressure is a powerful tool for…
Exotic stable calcium carbides: theory and experiment
Yan-Ling Li, Sheng-Nan Wang, Artem R. Oganov +3
It is well known that pressure causes profound changes in the properties of atoms and chemical bonding, leading to the formation of many unusual materials. Here we systematically e…
Tetrahedrally coordinated carbonates in Earth's lower mantle
Eglantine Boulard, Ding Pan, Giulia Galli +2
Carbonates are the main species that bring carbon deep into our planet through subduction. They are an important rock-forming mineral group, fundamentally distinct from silicates i…
